Glad to be on the RALF! Instead of being a owner of a radar or laser system like most are on here, I install them for a living in clients vehicles. I have been installing radar and laser defense systems for about 15 yrs. Currently we install the Passport 9500ci or the Beltronics Stir plus with quad hp LI shifters. I look forward to seeing how you guys on here compare the different radar and laser systems out there!
